Hull City manager Nigel Pearson has confirmed they have made a bid for Liverpool defender Daniel Ayala, reports BBC Radio Humberside.
Ayala, 20, made 12 appearances for the Championship side during a loan period last season.
The Tigers were previously linked with a loan move for the Spaniard after Paul McShane was ruled out for several weeks with a calf injury.
Pearson said: "We've enquired after the player, we've put a bid in."
He added: "Whether that develops before the weekend I don't know.
"We'll try and do it as we always do it, in a quiet way, but for sure that's where we're at."
The Seville-born centre-back has made five first-team appearances for Liverpool, and also had a loan spell at Derby last season.
